When we consider all the major JavaScript frameworks that are popular at this point in time, AngularJS is one of the names which rings high in our ears. It has been phenomenal since its launch, and has triggered many fantastic applications as well as websites. It follows the same queue of modular view frameworks by providing simplicity of the web development process. An AngularJS development company can create simple as well as complex applications by giving uniform consideration to testing and creation.

Why AngularJS 2.0? And how the controversies spur?

AngularJS 1.3 version has some performance issues while dealing with smart phone operating systems. The new version which is scheduled to be launched at the beginning of 2016 is more focused on the creation of mobile applications. In addition to the mobile centric approach, AngularJS 2.0 will be much up to date in terms of modules and compatible with all modern browsers. It will be modern in every sense including the performance. Still the shift to the advanced version from 1.3 was done with any migration path. The entire codes were rewritten without any backwards compatibility leading to an uncertainty. Existing projects in AngularJS 1.3 will have to be fully rewritten to make all that updated to the new version.

What are the major updates?

To say it in simple terms, it is not just a single update, but drastic in terms of changes, even the vocabulary. Here let us check out the worthy ones.

1. AtScript the superset of ES6 is used for the creation of AngularJS 2.0 Those who are not familiar with ES6 can make use of ES5 to develop applications.

2. Injecting annotations while creating instance of a class has been made easy.

3. Child injectors that have all the features of the parent modules were added to call various objects automatically as per the need of developers.

4. Far improved library having powerful functions has been implemented.

5. New dynamic loading trait is implemented to ease the development process. Using it developers can create controllers and directives on the run itself.

6. Component, Decorator, and Template directives are imported for smooth working with HTML, CSS so on.

7. A logging service named diary.js is implemented to identify where most of the time is spent on applications.

Child router, Screen Activator, and plenty of routing solutions such as Location services, URL Resolver, JSON configurations, and Document Title Updates so on have been extended. All these inclusions have made AngularJS 2.0 more powerful than the current 1.3 version. The architecture of this program is asynchronous, hence all JS developers will find it suitable.

Bottom line

The developers are working on it to deliver maximum output by improving the level of performance to a higher level. The Controversy and uncertainties relating to the updates is expected to be solved at a positive note by the end of this year with the release of AngularJS 2.0.
